Impact of xylanases on gut microbiota of growing pigs fed corn- or wheat-based diets.

ABSTRACT: This study investigated the effects of xylanase supplementations with cereal-based diets on nutrient digestibility and gut microbiota of growing pigs. A total of 96 individually penned pigs (initial BW = 22.7 ± 0.65 kg) were allotted to 12 treatments and subjected to a completely randomized block design experiment. Pigs in each treatment were fed an isocaloric wheat-based or corn-based diet with or without 1 of 5 types of xylanase supplements (XA, XB, XC, XD, XE). On d 42, all piglets were euthanized to obtain ileal and cecal digesta for microbial analysis, which involved high-throughput sequencing of the V1 - V3 regions of 16S rRNA gene. Corn- and wheat-based diets differed (P < 0.05) in digestion characteristics. Dietary treatments affected the alpha- and beta-diversities of microbiota i
